Lightroom Classic: Resource hungry and driver issues

I hope someone at Adobe is taking note of all the problems that users are having since the "upgrade" to LR Classic.

Lightroom Classic crashes frequently and causes my computer to abruptly shutdown. The new LR appears to be extremely resource hungry. Slow...Frequent Crashes...Black Screen...Images Not Displaying...Crashes during Import...Serious Lag when changing sliders in Develop Module.  

According to other user complaints, LR does not work well with some graphics drivers. My AMD R9 290 video card with the latest driver 17.7.2 is no exception. Images freeze or show black in LR. When I turn OFF the GPU feature in  Preferences,  LR displays the image but this kills speed and efficiency.

Users deserve better and Adobe should fix these issues. Some of the new features appear promising, but I am very disappointed in the latest LR version. As a user I expect a stable version when I "upgrade".

For me Lightroom Classic CC always consumes a lot of CPU power. A minimum of 100% CPU on a quad-core 2016 MacBook Pro in my case. This is when it's sitting idly in the background, not doing anything in particular like syncing or generating previews. You can see in the chart below the steady load. I've noticed worse battery life when LR Classic is running and I suspect this is why. See screenshots below from iStat Menu and Activity Monitor.

John, try the tip #2 https://helpx.adobe.com/lightroom/kb/crash-gpu-directx-enabled.html to see if you can reclaim some performance loss due by opting for OpenGL based image rendering. 

Stephen's issue of higher cpu usage during idle is probably due to Lr proactively updating the stale standard previews for the last edited photos (in the last 2 days) during idle (so that when walk the photos in library, there would be no additional delay). Stephen, try following the same tip #2, but replace config.lua the download link to https://adobe.ly/2yMYdY4 and see if it helps.
